Vintage and from the same estate sale...not a brand new knife....
 
BEAUTIFUL HANDLE MATERIAL!  Please see all pictures of this beauty.
 
THIS IS AN EARLY FISHING KNIFE.  I BELIEVE IT WAS MADE BY MARTTINI PER THE FISH AND "M" LOGO ON THE SHEATH.
 
The handle looks to be a heavy lacquered material but im not 100% sure.  Please see pictures.  The sheath is hand tooled and has a loop at the top for hanging on a belt.
 
Condition:  Handle has no cracks or chips.  The blades have some light signs of age.  Nice and strong.  No issues found with the sheath.
 
9 1/4" total length when in the sheath.
